FRANK E. DE BR'UN, OF CHICAGO,- ILLINOIS, ASSIGNOR TO THE NEGEDAH KANUI'AC- TUB-ING CORPORATION, 01

CONSIN.

a citizen of the United States, residin at hicago, in the county of Cook and of Illinois, have invented certain new and useful Improvements in Power-Plant Mountings, of which the following is a specification, reference being had to the accompanying drawings, characters marked thereon, which forma part of this specification.

It very frequently happens that persons using small power plants have occasion to operate different mechanisms, located at somewhat widely separated points, and find it desirable to have the motor engine portable. For example, a farmer may have the dynamo of his lighting plant in one location, his centrifugal creamers and other machinery in other locations. It is, manifestly, expensive to use a plurality of power plants or engines to run the separate machines.

One difliculty experienced in moving portable engines from one location to another has been the inability tostabilize the base of the engine in the several locations, in order to produce the best results.

The rincipal object of this invention is uce a power plant mounting that may be used in a fixed position adjacent to the particular machine to be operated by the engine, each mounting so arrangedas to properly support a carriage or truck upon which the engine is to be mounted, and so arranged that when the carriage is rolled upon a particular base or mounting, the carriage and its engine will be raised from the base line or ground sufficiently to raise the wheels of the carriage therefrom and transfer all of the weight of the engine and carriage directly to the mounting.

- The details of my invention and its many advantages will be apparent as I proceed with my specification.

In that form of device which I have chosen to illustrate my invention, as shown in the accompanying drawings, illustrates in a side elevation the dynamo of a lighting plant, an engine mounting adjaand carriage upon and secured to said mounting. Fig. 2 is an end elevation of the same.

. Fig. 3 is a side elevation of the same with the engine and carriage mountin Fig. 4 1s a side elevation carriage upon a mounting.-

Fig. 5 is a plan view of shown in Fig. 3.

Fig. 6 is a plan view of a slightly modified form illustrating one means of directlng the carriage properly to, the mounting, Fig. 7 is a vertical sectional view, enlarged, of a detail showing one means of securing the carriage to the mounting.

In said drawings, A represents as a whole, a dynamo of a lighting plant, provided with a base a, suitably bolted to a fixed foundation block F. represents as a whole, the power plant or usual hollow pedestal b and adapted to be suitably bolted to the top or table surface of a carriage C.-

The dynamo A is verse shaft lcarrying on one of its ends a coupling gear 2. A shaft 3 on the power plant is provided with a spur gear 4 adapted to mesh with and operate the spur gear 5. his gear 5 is mounted upon a rotatable sleeve 6 which lattermay be eccentrically mounted upon a transverse shaft, not shown in the drawing. To the outer end of said sleeve 6 is secured a coupling or gear7, adapted to engage the coupling or gear 2 of the dynamo A. 8 is a handle attached to the coupling 6 and adapted to be moved so as to place the gears 4 and 5 in mesh, as shown in Fig. 1, or to raise the gear 5 out of-mesh with the gear 4 as shown in Fig. 4. The shaft 3 is provided with the usual fly wheel .9 and may also be provided with a pulley wheel 10. The crank 11 enables the operator to start the engine in the usual manner. 1 i

The carriage C will conform in general dimensions to the base of the engine to which it is bolted, and comprises two longitudinal side members 12, 12, and transverse connecting members 13. The side members 12 have inwardly directed flanges 14, the top surfaces of which constitute a bearing surface for the base of the engine. The under surfaces ofsimilar inturned flanges 15 provide a shoulder or support for the carthe structure engine mounted upon the provided with a transriage C, when it rests upon the mounting presently to be described. A

In said under surfaces of the flanges is cut a longitudinally extending recess or roove 16 adapted to engage a track 17 %referably the contour of the recess 16 and of the block 17 will be complemental.

The carriage mounting, characterized as a whole by the letter M, COIDIIlSQS two side bars or'supports 18, prefera ly of channel iron, with their flanges directed mwardlly; the side bars 18, 18, being ]01I16d. by connecting cross bars 19. In some cases, the mounting M may be integral with the foundation block F, as for exam la in the form shown in Figs. 1 and 3. n other instances, the

mounting M rests.

mounting M will terminate at oneend with a back stop S. The two side members 18, 18, of the mountin M, are in parallel relation, as clearly in icated in Figs. 2, 3 and 6, and are considerably lon er than the length of the side bars 12 o the carriage C. The tracks 17 extend from the stop S toward but not quite to the outer ends 20 of the side bars 18 and the top surface of said side bars 18 is tapered or inclined downwardly toward the ends 20 as shown at 21,

Gr indicates the ground line on whlch the At either side of the front ends 20 of the mounting M, I place suitable guide bars 22. The carriage C Wlll be provided at each side with rotatable wheels 23 mounted uponaxles 24 whereby the power plant and carriage may be moved from one place to another along the ground line G when the power plant and carriage are disengaged from the mounting M. When the carriage C is upon the mounting M the height of the tread of the rails 17 above the ground will be such as to clear the'tread of the wheels 23 from the ground. 25 is any suitable wheel or draw bar that may be secured to the carriage C and by which the carriage ma be moved bodily along the tracks 17 an down the inclines 21 until the wheels 23 engage the ground G in restoring the carriage to the mounting M. The latter will be approached from the ends 20 as indicated by the dotted wheel lines 23, the wheels passing in the space between the guides 22 and the side bars 18. Presently the carriage will contact with the inclined surface 21 and the carriage will be pushed forward until the grooves or re cesses 16 engage the tracks 17. y

In the modification shown in Fig. 6, I have dispensed with the side guide bars 22, 22, and formed guiding surfaces 26 upon the outer edges of short extensions 27 to the side members 18. In Fig. 6, the first or approach position of the wheels 23 of the carriage is indicated in full lines and the final position indicated in dotted lines, whereby it will be seen that in moving the carriage toward and longitudinally of the mounting M, .the carriage wheels will contact with one or the other of said guide surfaces 27 and thus properly center the carriage with respect to the mounting M sov clearly shown in Fi 7, comprising a downwardly projectin ange member 28 from each of the outsi e bars 12 of the carriage. These two flange 28 will straddle the two Side members 18 of the mounting M. A set screw or locking bolt 29, operated .by the handle 30 will be assed through the flanges 28 until the end 0 the set screw 29 will 1mpinge against the surface of the side bar 18; thus the carriage Cmay be conveniently and securely locked to the mounting M.

It is recommended that a plurality of mountings M will be used in connection with one power plant and carriage C and that said mountings will be placed at difi'erent places about the factory or farm where different machines are conveniently located.

The purpose of the pulley wheel 10 is to enable the user to place a belt thereover and thus couple the power plant with the machine WhlCh is desired to be operated by said power plant. The pulley 10 may, obviously, connect the power (plant with the dynamo A, but I prefer the irect cou ling indicated by the coupling or gears 2, 7, as indicated in the drawing.

- As shown, the carriage C is of the relative size of the base of the power plant. B and the power plant and carriage will be mampu Obviously the axles 24 of the carriage C may be directly connected with the power plant in a familiar manner so that the carriage C may be operated by the power plant if. desired.

It will be manifest from the foregoing that when the power plant is con led up with the dynamo A and the carriage locked by the bolts 29, to the mounting M, with the tracks 17 filling the longitudinally arranged grooves 16, the engine and base will have a firm, secure and rigid position not only with respect to the mounting M but to,

the machine (in this instance, the dynamo) which it is to operate. Similarly, when the carriage C and the engine B are moved over onto the mounting illustrated in Fig. 4, and in juxtaposition to another machine to be operated from the pulley 10, the engine and carriage will be securely and practically held for all operative purposes; the carriage being1 locked by the bolts 29 to the mounting M w ile the end of the carriage rests squarely against the stop or abutment S. It will be understood of course that in all cases the mounting M is of such size and weight as to ated by the draw bar or handle 25.

rest rather securely by gravity upon the ground but it will also be clearly understood that the several mountings M may be locked to or built up from the ground in a familiar manner.
